Slate or blackboard cleaner



UNITED STATES PATENT OFFICE.

W. ELLIS WISE, OF WILLIAMSPORT, PENNSYLVANIA.

SLATE OR BLACKBOARD CLEANER.

SPECIFICATION forming part of Letters Patent No. 264,811, dated September 19, 1882.

' Application filed April 6,1882. (No model.)

To all whom. it may concern: Be it known that I, W. ELLIS Use, a citizen of the United States, residing at Williams port, in the county of Lycotning and State of panying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

, Figure l is a perspective view of the present invention. Fig. 2 is a vertical centralsection through the device.

This invention belongs to that class of devices known as slate or blackboard cleaners, and the novelty in the present instance consists in the construction and combination of the parts, all as will now be more fully set out and explained.

In the accompanying drawings, A denotesa can, made preferably with sloping sides, so as to have a neck, a, at its upper end, to which is fixed the flaring top or mouth-piece a. This serves as a seat or receptacle for the sponge B, and the lower part of which is secured in said mouth and upper part of the can A in any desired way. In fitting the mouth-piece a into the neck a, the lower end, a,ofthe mouth-piece is so made that it will project within the body of A, or any suitable construction for this end can be adopted, its object being to afford a retaining edge or points by or on which the sponge B may be held in position. At one side of the can is the nozzle 0, having any suitable stopper, D. Through this nozzle water can be introduced into the can for the purpose of keeping the sponge in a moist state,-and as much or as little can be kept there as is desirable.

Upon thebottoln of the can is secured in any desired waya drying material, E-soft leather, cloth, or any material or substance which can be advantageously employed for the purpose. I consider it preferable to attach or secure this drier by means of an elastic, c, in its upper edge. Thus when the drier is put on and over the lower part of the can A its upper edge in someother convenient way, so as tobeeasily moved and replaced. Also, 1 may have a handle on the body of the can to aid in its use; andldo not confine myself to the precise shape of this can, as it can be varied in many ways without essentially departing from my abovedescribed invention.

It is obvious that the peculiar method of uniting the mouth-piece to the top of the can may be varied, as by merelyjoining the two edges together, and in other ways, without de parting from the scope ot'this invention.

This device will be very convenient, when made of proper size, to use as a cleaner for a slate, and for blackboards a larger size may be employed. 1 t is very cheaply made, and is very durable.

' Having thus described my invention, whatI consider new, and desire to secure by Letters Patent, is-

1. In a blackboard-cleaner, the combination of sponge B with the can A, having neck a, and mouth-piece at, having retaining-edge a projecting inside the body of A,substantially as described.

.2. The slate or blackboard cleaner herein de- V W. ELLIS WISE.
